Double-cup piston for disc brake comprising electromechanical parking brake device

The utility model relates to a double-cup-shaped piston for a disc brake comprising an electromechanical parking brake device. The utility model is based on the task. An improved compromise between simple maneuverability, reasonable component flow in piston manufacturing, reduced hydraulic volume consumption in cooperation with wheel brake peripheral components, and increased fatigue strength at maximum load sets is achieved. The utility model relates to a disc brake, in particular for heavy-duty applications with an electromechanical parking brake device. This task is solved in this way, according to the utility model, a piston wall (2) is provided, which is designed to be supported on the rear plate (4) of the friction lining (5) by means of a free edge (3) on the one hand, and wherein the piston (1) has an integral dome (6), which forms an open receptacle (7) for the adjustment device (SV) in the opposite direction to the edge (3) of the piston. 本实用新型涉及一种用于包括机电的驻车制动装置的盘式制动器的双杯形活塞，本实用新型基于的任务是，实现在简单的可操作性、在活塞
